I’m currently in my 7th year of post-secondary education. I used to be able to devour books by the hour when I was in high school (I didn’t have a cellphone till first year university). I applaud you for finding a way to get these students back on track, Peter!

Have you seen this article? The professors have a “tech break” during class, or even give out a participation mark when students leave their cell phones at the front.
